Thanku HiveMQ for making such informative videos, it really helped me and my friends. At 0:44 sir tells that MQTT features reliable communications over unreliable channels, what's the physical significance of this? Does this meant that MQTT communication will be proper even for poor net connectivity and less bandwidth. Pls help me with this doubt
Hi Dhanesh, thanks for your feedback. Regarding your question: MQTT was developed with poor network connectivity in mind. This results in it having mechanisms such as QoS levels (and their guarantees) to help mitigate unreliable physical connections. I hope that answers your question.
Hi Martini, thank you for your feedback. Glad the video was useful to you. You can refer to our blog series for more information --> www.hivemq.com/mqtt-essentials/
Nice video! Congrats! I just couldn't understand clearly the idea that MQTT is a binary protocol. What makes MQTT classified in this way? Thanks in advance.
Hi Bruno, Thanks for your feedback, we really appreciate it. For any technical discussion, I can highly recommend our community forum. Here is the link to the category in which your question will fit in community.hivemq.com/c/mqtt/5
Hi Adduino, great question. While we have seen folks sending 25 frames per second, this is usually not what you would do with MQTT as it's not a streaming protocol. What is certainly done very often is having Machine Learning applications running on the image producing device which filters out outliers that are sent to the cloud then. If you just want to stream video, a proper video streaming protocol might be useful for the actual data transfer and MQTT is usually used then as a notification mechanism (e.g. for starting or stopping a video stream). Hope this helps!
Hi! We are glad you liked the video and it's useful to you. And, sorry that you are having trouble with the video's sound. It seems fine to us and we are not experiencing any echo. Can you kindly check your local sound settings?

Is this book at the Professional Training or Associate Training level?
The layout of the book is very beautiful and educational!
Best explanation I found on the internet so far. I did exactly as you said : blog + vid. Thanks for sharing :)
Great to hear!

@@HiveMQ Thanku
I wish you had videos for sittings of the gateway using the HiveMQ Cloud cluster. Thanks.
Nice video! Congrats! Thanks !
I couldn't not understand how openssl is used MQTT for secure communication. Can you please clarify?
Hi Kavie, TLS can be used to encrypt the communication between all communication participants involved in message exchange
Omg you are so good at explaining stuff!! Like wow, I understood everything. Could you post the text where you read from? Thank you

4:40 entender específicamente la relación entre mqtt y tcp
Technically it doesn't require TCP.. it requires a connection based protocol, that could be TCP or any other stream based protocol, but not UDP.

Is there any protocal is not data-agnostic?
Can we send video frame over MQTT. forexample 25 frames per second ? or 20 frames per second ?

I try it before.
It works, but there are other tools that are better for doing streaming, like Gstreamer
Excellent vidoe, but sound is terrible (please remove sibilance, and echo)
